Title: Steplessly-adjustable friction drive - has intermediate discs formed with curved peripheral profile and main discs slidable on shaft
Inventor: HAINMUELLER SIGURD
IPC: F16H15/28
Filed: 1978-02-24
Abstract: The steplessly adjustable friction drive unit is particularly for motor vehicles, having coaxial driving and driven discs, each with a concave peripheral face, against which intermediate friction discs run. The latter have shorter peripheral faces and rotate on brackets tilting in the housing on axes crossing and clear of the unit axis so as to vary the ratio. The discs are pressed against the driving and driven ones. The intermediate discs have a peripheral profile which is curved in cross-section. The mating faces of the driving and driven discs are so shaped that in each position of the intermediate discs, the point of intersection of all disc axes is likewise that of the tangents at all contact points between discs.

Title: Impact subjected industrial type swing door - has reinforcing bars and hinge fittings inside monolithic hollow ductile plastics leaf
Inventor: BROWN JAMES W
IPC: E06B3/86
Filed: 1978-04-07
Abstract: The door can be exposed to impacts likely to be encountered in industrial or similar surroundings. It has a hollow ductile plastic body (12) of high rigidity formed in a single moulding process to incorporate two spaced sides (14, 16), top and bottom pieces (18, 20) and interfacing vertical edges. All these are monolithically formed. Insulating material is applied inside and connected to interior surfaces. This has reinforcing bar-type elements embedded in it, at an interval from sides and edges. Near one edge there are elements for attachment of hinges, for door mounting on a post. The unit can be safely used as a swing door in areas subject to impacts.
Patent DE-2816466-A1 (DE)
Title: Building elements, esp. panels, made of gypsum and fibres - where gypsum in panel is dehydrated in autoclave, followed by pressing and rehydration in moist atmos.
IPC: C04B28/14
Filed: 1978-04-15
Abstract: A mixt. is made of CaSO4, 2H2O (gypsum), water, and fibres; and the mixt. is moulded. The moulding is then subjected to 1.5-10 bars at 115-180 degrees C., so that the dihydrate loses water and is thus converted into a bonding material, followed by exposing the moulding to conditions which reconvert the CaSO4 contg. a low amt. of water into the dihydrate. The moulding is dried. After heating at 115-180 degrees C, the moulding is pref. cooled to 100-80 degrees C., followed by further cooling and pressing at 5-100 bars in an atmos. of 80-100% relative humidity (RH) for 2 h to 7 days. The moulding is then dried at 200-80 degrees C. The initial mixt. may be continuously moulded on a conveyor belt and then rolled onto a drum to obtain panels of the required thickness. When using partly or completely dehydrated CaSO4, as a binder, e.g. CaSO4, 1/2H2O, the binder tends to block the prodn. appts. and also produces panels with varying properties due to varying properties in the binder. The invention uses CaSO4, 2H2O which is dehydrated and rehydrated in the mfg. process.

Title: Industrial plant to dry and cool processed sunflower seeds, etc. - uses atmospheric air in fluidised bed exhausting via predryer
Inventor: KIRIJOVSKIJ BORIS NAZAROVITSCH
IPC: C11B1/04
Filed: 1978-11-27
Abstract: A plant installation for drying and cooling vegetable oil-producing seed, partic. ground sunflower seed, after the seed has been subjected to a heating/wetting process, is of the type in which seed is dropped through a predrying chamber and from there to an air-fluidised, circular bed in the base of an upwardly divergent cyclone. Cyclone air is exhausted via the predrying chamber. The fluidised bed conveys the prod. over an annular, horizontal path and then drops it into a discharge screw conveyor. The predrying chamber now contains adjustable, slated screens, i.e. 'venetian' type, by which the angle of air flow w.r.t. prod. flow can be regulated, e.g. between 0-90 degrees. Inside the cyclone, an upwardly convergent cone leads exhaust air towards the predryer connection which has helical slots back into the convergent cone. The fluidised bed air chest has a downwardly convergent cone connected into the top of the discharge screw conveyor. This dryer/cooler is also for oatmeal, pearl barley, etc. The single, much more compact plant can process 500 tonnes in 24 hrs., compared with 200 tonnes from earlier, larger installations. Prod. quality is enhanced by much more homogeneous treatment. Atmos. air used as the cooling/drying medium is filtered through incoming seed in the predryer. This cleans the exhaust and raises prod. yield by eliminating loss of fines.

Title: Automatic feeding of narrow fabric to sewing machine - incorporating guillotine to cut required length from continuous supply
Inventor: HEYMANNS KURT
IPC: D05B35/06
Filed: 1979-05-14
Abstract: A mechanism for presenting to the sewing point of a sewing machine a lining material of narrow fabric from a continuous supply, comprises a feed device for withdrawing a predetermined length of material from the supply and a cutter located in front of the needle for cutting the required length of material. The feed device works intermittently, at each operation advancing a length of material which is greater than the distance from the cutter to the sewing point, such that after the cut has been made the material is in the grip of the sewing feed dogs, and can be drawn freely through the feed device by the sewing operation. The device simplifies and speeds up the sewing operation by eliminating the need for the operative to pick up and manually position a pre-cut length of material. It prevents waste of materil by enabling the cut length to be matched accurately to the length required.

Title: Panelled gabled roof structure elements - have end mountings hinged to each other at ridge, and to eaves supports
Inventor: BRUNOTTE HEINZ DIPL ING
IPC: E04B7/02

Title: Shading control for photocopier - has aperture and exposure control to correct for variation in photo-transistor material response
Inventor: WEIDLICH DIETER
IPC: G03G15/043
Filed: 1979-05-31
Abstract: An automatic contrast control for a photocopier has adjustable apertures in the scanner to modulate the light intensity w.r.t. time for successive copies. The adjustment is such that a constant contrast is obtained, with a constant density. The apertures are linked to a pivot driven by a bimetallic strip or spiral. This provides an exposure time control, with longer down times between copies correspondingly corrected for. The adjustment takes into account the variation in response of the sensitive layer on the process drum, and the recovery period for the layer.
